Detailed Description
Fig. 1 and 2 show a schematic perspective view of a cover and a schematic plan view of the cover according to the present utility model. The utility model relates to a shaftless magnetic drive pump front cover structure, which is mainly characterized in that a top wall 10 and a side wall 12 surrounding the top wall 10 are used for defining a cover body 1, a space 14 is formed by the top wall 10 and the side wall 12, a plurality of locking holes 120 are formed by the side wall 12 in a surrounding manner, a clamping structure 122 is formed on the inner side of the side wall 12, a first conveying structure 16 is arranged at the central position of the cover body 1 and is communicated with the space 14, and a second conveying structure 18 is arranged at one side of the cover body 1 and is communicated with the space 14.
The fastening structure 122 extends from the communicating position of the second conveying structure 18 in a clockwise direction and is not connected back to the communicating position of the second conveying structure 18, the fastening structure 122 extends from the communicating position of the second conveying structure 18 in a tapered manner, due to the tapered effect of the extending direction and the width of the fastening structure 122, the liquid is enabled to generate a vortex effect after entering from the second conveying structure 18, and the whole flow is smoother, meanwhile, due to the fact that the fastening structure 122 is not in a whole circle of structural design, the plastic usage is reduced, and the manufacturing cost is reduced.
In addition, the cover 1 is provided with a mounting structure 2 at the first conveying structure 16, and the mounting structure 2 includes a fixing member 20 and a plurality of supporting members 22 connected to the cover 1 around the fixing member 20.
Referring to fig. 3 and 4, a schematic view of the use state of the assembled cover and a schematic view of the assembled side view of the assembled locking cover are shown. In the present embodiment, the main matching rear cover 3 of the cover body 1 is exemplified by a screw lock, wherein each through hole 30 arranged around the rear cover 3 corresponds to the locking hole 120 on the cover body 1, and the through hole 30 and the locking hole 120 are penetrated by a bolt to complete the assembly of the rear cover 3 and the cover body 1 and shield the space 14.
